Benefits of technology

The present disclosure is about a display device that can improve the amount of light that comes out from an organic light emitting layer. This is done by creating patterns on the first electrode and then using a color filter to block out some of the light emitted from the organic layer. This makes the light that is emitted from the organic layer have better clarity and can pass through the color filter without being affected.

Problems solved by technology

However, if the polarizer POL is arranged on the organic light emitting layer, light emitted from the organic light emitting layer is partially shielded by the polarizer POL, whereby a problem occurs in that light transmittance is deteriorated.
However, even in this case, there is a limitation in improving light transmittance due to the color filter.
This problem occurs more seriously in case of a display device, which requires ultra-high resolution, such as a head mounted display.

Abstract

A display device includes a substrate provided with a first subpixel and a second subpixel; a first electrode provided on the substrate, including a first sub electrode provided on the first subpixel and a second sub electrode provided on the second subpixel; a transparent electrode including a first transparent electrode provided to cover the first sub electrode and a second transparent electrode provided to cover the second sub electrode; an organic light emitting layer including a first organic light emitting layer arranged on the first transparent electrode and a second organic light emitting layer arranged on the second transparent electrode; a second electrode arranged on the organic light emitting layer; a first bank provided between the first transparent electrode and the second transparent electrode to partition the first subpixel and the second subpixel from each other; and a first color filter arranged to correspond to the first subpixel.

Description

BACKGROUNDTechnical Field[0001]The present disclosure relates to a display device displaying an image.Description of the Related Art[0002]With the advancement of the information age, the demand for a display device for displaying an image has increased with various forms. Therefore, various types of display devices such as a liquid crystal display (LCD) device, a light emitting display device, an organic light emitting display device, a micro light emitting display device, and a quantum dot light emitting display (QLED) device have been recently used.[0003]For an organic light emitting display device, red, green and blue pixels of an organic light emitting layer are formed and then a polarizer POL is arranged thereon to prevent external light which is reflected from entering a user's eyes. However, if the polarizer POL is arranged on the organic light emitting layer, light emitted from the organic light emitting layer is partially shielded by the polarizer POL, whereby a problem occ...
